We report the presence of extensive, transcriptionally controlled oscillations in the C. elegans, developmental transcriptome. Furthermore, using ribosome profiling, we show that these oscillating transcripts are actively translated. Overall design: Examination of three timecourses that were collected over C. elegans development and analyzed by RNA-seq of mRNA libraries

View SamplesWe perform RNA sequencing and ribosome profiling time course experiments to examine the effect of fully dysregulating all let-7 targets (in let-7(n2853) animals), partially dysregulating only LIN41 (in lin-41(xe11) animals) or fully dysregulating all let-7 targets while partially dysregulating LIN41 in lin-41(xe11); let-7(n2853) double mutant animals. We conclude that effects on gene expression in let-7 mutant animals are largely and quantitatively explained by dysregulation of LIN41 as its primary target. Furthermore, we identify direct LIN41 target genes regulated on the level of translation or mRNA abundance. Overall design: Total RNA-sequencing time course experiments sampling synchronized worm populations of different genetic backgrounds every two hours over the course of development from late L2/early L3 stage to late L4/Young adult stage.
LIN41 Post-transcriptionally Silences mRNAs by Two Distinct and Position-Dependent Mechanisms.

View SamplesMetastasis of human tumours to LNs is a universally negative prognostic factor. LN stromal cells (SCs) play a crucial role in enabling T cell responses, and since tumour metastases modulate their structure and function, this interaction may suppress immune responses to tumour antigens. However the SC subpopulations that respond to infiltration of malignant cells into human LNs have not been defined. Using microarray, we sought to assess gene expression profiles of two distinct SC subpopulations isolated from melanoma-infiltrated LNs.
